A premature infant, also referred to as a preterm baby, is born before the completion of 37 weeks of gestation. With advancements in neonatal care, the survival rates for preterm infants have improved significantly, but they remain at higher risk for medical complications and developmental delays due to underdeveloped organs and systems. Classification of Prematurity
Premature ejaculation (PE) is one of the most common male sexual dysfunctions, defined as ejaculation that occurs sooner than desired—either before or shortly after penetration—causing distress or frustration for one or both partners.

Pregnancy is a transformative physiological state, characterized by the development of a fetus within the uterus, beginning with conception and culminating in childbirth. Spanning approximately 40 weeks, it is traditionally divided into three trimesters, each marked by significant changes in maternal physiology and fetal development. Understanding these stages is critical for ensuring optimal maternal and
Precocious puberty refers to the onset of puberty at an unusually early age—before 8 in girls and before 9 in boys. This condition accelerates the body’s physical and hormonal development far earlier than expected, often leading to emotional, psychological, and physical implications that warrant medical attention.

Pre-op apprehension, also referred to as preoperative anxiety, describes the psychological distress experienced by patients before undergoing surgery. This emotional state, characterized by fear, worry, and tension, is a common yet often underestimated challenge in surgical care. Addressing pre-op apprehension is essential not only for patient comfort but also for improving surgical outcomes, reducing perioperative
Pre-menopausal osteoporosis refers to the loss of bone mineral density (BMD) in women prior to the cessation of menstruation. While osteoporosis is often associated with post-menopausal women, a growing body of evidence highlights its presence in younger females. This condition, though less common, carries significant morbidity due to increased risk of fragility fractures, chronic pain,
Pre-existing hypertension during pregnancy, also known as chronic hypertension, refers to elevated blood pressure diagnosed before pregnancy or before 20 weeks of gestation. This condition significantly influences maternal and fetal outcomes and requires vigilant monitoring, targeted therapy, and multidisciplinary care. Classification and Diagnostic Criteria Pre-existing hypertension is classified by the American College of Obstetricians and
Angina pectoris is a clinical manifestation of myocardial ischemia, typically triggered by increased oxygen demand during physical or emotional exertion. The resulting chest discomfort stems from an imbalance between myocardial oxygen supply and demand. Pre-exertional prophylaxis of anginal pain is a cornerstone of ischemic heart disease management, aiming to reduce the frequency and severity of
Posttransfusion purpura (PTP) is a rare but potentially life-threatening transfusion reaction characterized by severe thrombocytopenia occurring 5 to 10 days after a transfusion of blood products. This alloimmune disorder predominantly affects previously sensitized individuals and is most commonly associated with antibodies against human platelet antigen-1a (HPA-1a). The sudden and profound drop in platelet count places
